Android audio record and processing

Question

I want to program a app about audio signal processing on android. First I should record the sound using the mobile app. Then I want to get the raw data (an arraylist I think) and do FFT on it. With the data in frequency domain, I want to do some processing, mainly a noise reduction method called 'spectural subtraction', then do IFFT. Finally write the data to a .wav file. I'm new to Android and don't know which API suits my desire and where I can find FFT code. So I'm asking for help and thanks a lot!
